SPECIFICATION forming part of Letters Patent No. 515,520, dated February27, 1894.

Application filed September 5, 1893. Serial No. 484,868. (No model.)

To aZZ whom it may concern.-

Be it known that I, ENOOH E. DE KALB, a

.citizen of the United States, residing at Syra- My invention relates toimprovements in devices for mounting, operating and locking swingingwindows, and relates to improvements on the devices shown, described andclaimed in Letters Patent for devices for mounting and operatingswinging windows,

dated December 2, 1890, No.4 l1,943, and consists in certain novelimprovements in bracket-slip-hinges and locking devices whereby saidslip hinges are locked at certain predetermined points.

The invention is designed more especially for use on street cars andrailway coaches, where all the Windows on the same side of the car canbe set open to any desired extent and then looked in that positioneither on one side of the window or the other, or both sides at the sametime by my improved locking bar or rod.

The invention further consists in the novel construction and arrangementof the parts hereinafter described, illustrated in the drawings and moreparticularly pointed out in the claims hereunto appended.

Referring to the drawings: Figure 1 is an elevation of a portion of arailway car having a portion of the inner casing removed, and showing mynew locking device applied to the windows. Fig. 2 is an elevation of oneside of the window frame having a portion thereof removed, showing thedrop bar and hinges in position, with the outer ends of the lattersecured to the sash. Fig. 3 is a portion of the locking bar showing thelugs or stops thereon, and the links and levers on the ends thereof.Fig. 4 is a vertical section of the the window is being opened orclosed.

casing, taken on the line a:a2, Fig. 5. Fig. 5 is a longitudinal sectionof the casing, showing the construction thereof. Fig. 6 is a top view ofone form of lug or stop on the locking bar. Fig. 7 is a side view of thesame. Fig, 8 is a side view of another form of lug on the locking bar.Fig. 9 is a cross section of the same showing one way of securing thelugs to the bar. Fig. 10 is a modification of the locking bar. Fig. 11is a cross section thereof on the line yy, Fig. 10. Fig. 12 is a sideelevation of the long leaf of the slip-hinge. Fig. 13 is a top viewthereof. Figs. 14, 15 and 16, views showing modifications of the shortleaf of the hinge. Fig.1? is a perspective view of the hinge. Figs. 18and 19 are views showing the short leaf of my improved slip-hinge. Fig.20 is a detail view showing the short leaf of the hinge applied to asection of the sash.

Similar letters of reference indicate corresponding parts in all thefigures where they occur.

A, A, A, represent the window frames on the same side of a railway orother car, and B, B, B, the sashes therefor.

G is a casing that is secured to the uprights just inside the windowframe, and consists of two parts the body 0 and the plate or cap 0 thatfits thereon and forms in the said casing a horizontal way. in whichworks a bracket slip-hinge. Under the capo is a vertical groove orchannel 0 in which works a drop bar F for securing the hinges in certainpredetermined positions. This cap 0' is attached to the casing in anysuitable manner. The interior of this casing is somewhat curved, asshown in Fig. 5, for the purpose of permitting the slip-hinge a slightlateral play when The cap 0' is provided with lugs c on its under sidefor the purpose of more accurate adjustment to the body 0.

D represents a bracket slip-hinge, which consists of the long leaf d andthe short leaf (1'. The long leaf is provided on one end with a stop orlug (Z and on its upper edge with notches 0 0 the notch 0 has thestraight edges and is next to the hinge end of the leaf, while the othernotches 0 have, preferably,

sloping edges, as shown, and are between the notch 0 and the end of theleaf on which the lug or stop d is situated. Instead of two notches, asshown in the drawings, there may be any number desired. The short leaf dis provided with a plate 61 which, when the leaf is in position on thesash rests on the outside thereof forming a brace for the hinge andprevents the window splitting at that point. On the outer end of theshort leaf is a bead or flange 61 which, when the leaf is secured on thesash in proper position rests on the inside of the sash and forms anadditional brace for the said hinge. Instead of the plate 01 shown inFigs. 18 and 19, I may use the form of leaf shown in Figs. 15, 16 and17, in which latter form I use lugs d on the under side of the leafwhich fit in recesses in the sash. In practice I find that either leafmay be used to advantage, depending somewhat upon the thickness,hardness, the, of the sash to which it is to be applied. The leaves cland d are jointed as set forth in the drawings. The long end 61 of thehingeD fits in the casing O and slides freely to and fro therein, thelug d on the leaf 0?, runs in a groove or slot 0* in the casing andprevents the withdrawal of the leaf cl from the casing, as isevident. Inthe use of this device on car windows there are usually four hinges to"each window, but there may be a greater number if found desirable, withusually two of the hinges on each side of the window, so that whendesired the windows may be opened on either one side or the other, or ifdesired, entirely removed.

F, F, are drop bars Working in vertical grooves within the window frame,and the casings C O secured thereto which casings are fastened to theframe or uprightby the cap 0' thereof, each of the drop bars isprovidedwith two lugs f, f, for engagement with the notches 0 or 0 on the upperedge of the long leaf (1 of the hinge D, as shown in the drawings. Thisdrop bar is provided with a button or knob f on the inner face of theframe A, which is secured to the said bar F and by means of which thesaid bar is raised to release the hinges D, and permit the window to beopened or closed, as desired.

G is a bar placed within the casingof the car and extends nearly theentire length thereof. This bar is placed within the casing just abovethe Windows, and immediately over the upper ends of the vertical dropbars F, and have secured to them lugs or stops 9, g, immediately overthe upper ends of the drop bars and in contact therewith, butindependent thereof, and are arranged on said bar in abontthe positionshown in the draw- Y The lugs g, g, may be of any size or shape,

and secured to the bar in any suitable manner. In the drawings I haveshown different modifications of this bar which I may use if founddesirable.

In Figs. 6 and 7 I have shown a modification of the locking bar. Thisbar is of the same construction as the bar G above doscribed, exceptthat the lug or stop G thereon does not extend below the lower edge ofthe bar, but is flush therewith, as shown in side elevation Fig. 7.

In Fig. 8 I have shown another modification of the locking bar. In thismodification the rod or bar Gr instead of having the lug or stop securedto it, the bar G is let into the stop g and secured therein in anysuitable manner, as shown in cross section Fig. 9.

It will be understood that I may dispense with the use of the longlocking bar in connection with my device, but I preferits-r use as thewindows are thereby securely locked in position and cannotbeunintentionally displaced.

At the ends of the barGare links it and h which connect the bar G with alever or handle- II by means of which the bar G is operated and causedtoslide longitudinally to lock and unlock thewindows of the car. Thelever II may be attached directly to the bar G, or instead of the linksit and h being interposed between the bar and the handle H,

I may interpose but one link, but I prefer to interpose the two links,as the liability of the bar being displaced by accident is greatlylessened. Instead of having the short lugs or stops g, g, as shown inFig. 1, over each drop bar, there may be one lug or stop g 'eX- tendingacross the top of the whole window. These lugs may be made integral withthe bar as shown in Figs. 10 and 11, or secured thereto, as in the caseof the smaller ones.-

Having described my invention, what I claim, and desire to-secure byLetters Patent, 1s-

1. The combination of a slip-hinge D having a lug and notches on itslongleaf, and plate (1 and flange d onthe short leaf, with a casing 0having a horizontal groove therein for the slip hinge and a verticalgroove connected with said horizontal groove, assetforth.

2. A slip-hinge composed of two leaves d t and d, the leaf d providedwith a lug on its end and notches on one edge thereof, and the shortleaf d having a plate d on its hinge end,
